I've been trying to wrap my head around this topic for the past two days and I can not find a clear answer.
What does this mean?
The number of voting files you can store in a particular Oracle ASM disk group depends upon the redundancy of the disk group.
- External redundancy: A disk group with external redundancy can store only one voting disk
- Normal redundancy: A disk group with normal redundancy stores three voting disks
- High redundancy: A disk group with high redundancy stores five voting disks
That I if +ORAOCR is at high redundancy that it has 5 voting disks which are on 3 disk/devices?
Or do I need to have 5 disk/devices?
Separate, but related question. When I run ocrcheck does this tell me I only have one voting disk? And thus, I can assume I'm running external redundancy on a single device?
